I have been using both the ISO-FLO and ISO-BOW for 10 days, I like the flexibility of both products. I use the ISO-FLO to mimic the overhead press at various heights, I use the ISO-BOW to facilitate dead lifts by wrapping 2 ISO-Bows around the Bullworker while sitting on the floor. I also have been using the Bullworker X5 Pro for 10 days and spend a lot of time with that in which I share in another review for that. I do want to start using the ISO-BOWs with the Bullworker for lunges and Bulgarian splits and others that Chrisman demonstrates in his videos. Itnhas become easier to incorporate these Bullworker products within my other workouts that I've been doing for several years.

I have had the ISO-FLO for a few weeks now and the longer I have it the more I appreciate it. There are so many ways that it can be used that it can almost be overwhelming at first, but I recommend just starting with the program that Bullworker has created in the very nicely made spiral bound manual that it comes with and go from there. The exercises in the manual are very well thought out and described. The flat feet straps work great and the hand grips are solid and comfortable. You can make working with it as intense or easy as you want to, I am amazed at how easy it is on the joints. It works great as a stand alone product, and if you have one of the Bullworkers like the Classic it pairs very nicely as an added strap to expand the Bullworker's capabilities. The cam buckle that is used to adjust the two straps is easy to adjust and holds itself in place, very solid. For such a simple looking device, it is surprisingly versatile and fun to work with. I look forward to adding more exercises to my routine in the future, mixing things up and keeping it fresh.

Don’t Know how it works because I ordered it over two weeks ago and still haven’t gotten it. I think they’re using 1970s shipping methods. I feel like I don’t even want it anymore, sort of like when a restaurant messes up your food and you just lost your appetite and don’t want it anymore. Maybe y’all should try different shipping methods because unless you do, I probably won’t buy anything else from this company

I love ISO FLO. Great workouts at home and small enough to take on the road. Can't go wrong.

Further to the below, a year on I can still scarcely believe that a couple of webbing straps and a carabiner can be such an effective training device. You really KNOW when you have used it. Initially I followed the plentiful online resources and as my experience with it grew I used this to branch out on my own. It truly is an amazing tool. So underrated and so far under the radar, buy one, learn to use it, keep an open mind and prepare to be amazed. One of the simplest, most cost effective things of any kind I have ever owned. I still can’t get my mind around it, it defies belief.
